I was just wondering why even with direct lighting (no bounce) such a setup would make the samples quality solution go way down in time. Just so I can understand what's going on under the hood so to speak. Makes no sense to me...LightwaveGuru wrote:3dreamstudios wrote:

Wrong Kernel. For that you have to use the Path Tracing Kernel. The Direct Lighting Kernel (with amb occ) can not Trace what you want...it have a reason that the name is DIRECT Lightning...so the DL KLernel is better for outside environment scenes...
if you need full tracing for all lights you need the PT or PMC-Kernel...

If there are not bounced rays, with DL in this situation, would I not get the rays coming through the window and only the rays inside (which solve quite quickly). Why is it that with a very bright light outside it reduces the quality solving timeline quite a bit?
load the PT Kernel....GI Clamp to 1 ...ray depth 8-12...good luck
and remember...OCtane is a PBR so the maximum sunlight is for linear set ups is in ideal 1 and not higher...if you go higher you produce from time to time hot pixel and artefacts.....(for example if you have much glossy nodes with out refl. blurring)snip lwuguru
